Get a Ziploc snack bag or equivalent. Put phone in and stay in the water all you want with phone in your pocket! Get the external charging cable too. Cheap on ebay and do not have to keep removing the usb cover

Ram, 23 Nov 2014Bought new Xperia Z3C. It has problem in sim card cover flap. Was loose and popping out itself... moreI don't know if you got a reply already or not, but for the seals pop out I found out that if you degrease them very well they will stay in for days instead of popping out every time in you pocket. But when I go in water I use clear tape to secure them properly... Sony has not made a good enough job with this seal design. Its quiet flimsy.

Z4C, 21 Nov 2014Just an opinion, I believe the reason why for this FRAGILE screen is due to increased IP ratin... moreMaybe but it's fairly certain that the Glass on the
BACK is not,GG3 or Dragontrail, it's just ,,,,,glass.

Sony in.the FUTURE needs to use,GG4 on the Front and flexible glass on the back -NOT,a flexible back , just glass that is very flexible and thus , nearly shatterproof.
OR GG4, on both sides.
OR a ceramic baked glazed metal back.

Ram, 23 Nov 2014Bought new Xperia Z3C. It has problem in sim card cover flap. Was loose and popping out itself... moreI've had the same issue as you, but after i bent a bit the flap cover's stick(tiny plastic stick that holds the flap cover between the port's hole and the flap cover), the flap cover was fixed.. you need to check if the stick aren't straight, make it straight, it worked for me.

SIM CARD PORT LOOSE:
Inside the port got a piece of paper can pull out, at the front of paper you need to fold it(FOLD TO SIM CARD THERE, JUST LIKE A L SHAPE) then your problem will be solve. Its doesn't the port problem, is the paper!!!

I made a query regarding scratch proof/resistant glass from xperia care through online chat with the customer service representative. As we can see most of the specs shown on gsmarena epecially when it comes to sony xperia line are scratch resistant/proof, they dont specify whether what type of glass did they use. They concluded that it may be either in form Corning Glass and Dragon Trail Glass or other glass material around.

Just an opinion, I believe the reason why for this FRAGILE screen is due to increased IP rating. Everything else can stretched during the molding process-except for the glass that Sony uses-it exceeded the yield strength limit though it did not cracked the screen on the process but as temperature/pressure varies or some factors-triggered when it is on users hands then already exceeded yield strength eventually results in a crack screen-this is just theoretical opinion not bashing Sony. This might have been overlooked during simulations.

I got mine just yesterday I can't explain how much I love this phone. Small and very comfortable to use, extremely fast CPU, one of the best on the market. The display is fine, but nothing spectacular. The camera is very good too, but not better than the 13MP on the Lenovo K900 models.

The performance is just unbelievable fast. It also got 43K+ points on Antutu 5.3.

I really love this phone and I hope to use it for a couple of years at least.

I have it since one week now. Really perfect. No cracks or any issue. I just hate all the default app you can't remove that have a lot of permissions (Weather Widget for example is a fucking joke on that side). But except this paranoid problem, everything is perfect.

The battery is excellent. I manage to not charge it for 3 days in stamina mode (disable Data when the screen if off).

I even tried it under under water, in my pocket while bicking, or in cold weather (Canada here)... I recommand to buy a case though, you never know when you will let it fall.
